【摘要】 目的 为寻找安全、无毒、高效的胃镜消毒方法，本文探讨应用氧化电位水（EOW）消毒胃镜的效果。方法 对临床污染的50支胃镜进行现场消毒试验。胃镜经去有机物处理后，以EOW生成机制备的EOW原液 〔氧化还原电位(ORP)1 100mV，pH2.7，有效氯40～50mg/L〕分别浸泡消毒5min、1min。于消毒前后共采样160例次。结果 EOW对胃镜表面自然菌杀灭率5min、1min组分别为99.94%、99.89% ，1min组腔内杀灭率为98.80%，平均每件杀灭率为99.54% 。结论 在彻底清除胃镜内、外有机物后，用EOW浸泡1min，能迅速杀灭微生物且因其无毒性残留可省去无菌水冲洗步骤，为临床安全、有效、便捷的消毒方法，经观察350例对胃镜无损害。

【Abstract】 Objective In order to find a method of disinfection for gastroscope which is supposed to be safe, less toxic and highly efficient, EOW was chosen for gastroscope disinfection in our hospital. Method Gastroscope was first washed with neutral liquids which were equally mixed by acid and alkaline water produced by EOW machine. It was then immersed in EOW(ORP 1 100mV,pH 2.7,effective chlorine 40-50mg/L) for 1 and 5 minutes. A total number of 160 samples were collected. Results The killing rate for natural bacteria was 99.94% in 5-minute group. In 1-minute group, the rate were 99.89% and 98.80% on the surface and inside of the gastroscope. The average killing rate was 99.54%. Conclusion It appeared to be a safe, effective and simple method for disinfection after termination of gastroscope. It could be directly used on patient without washing with aseptic water. No damage to the gastroscope was found.

当今各种内窥镜已被广泛应用，为防止和减少交叉感染，国内外一直关注其消毒方法的改进。近年来日本首先将酸化水应用于胃镜、牙钻等领域的消毒。我院采用西日本株式会社“圣太科”水生成机所产生的氧化电位水（简称EOW），进行胃镜消毒，本文仅报告细菌杀灭效果。
材料与方法
一、材料：
1.EOW：采用西日本株式会社SUNTECH-1000氧化电位水生成机，经电解,该水氧化还原电位(ORP)≥1 100mV，pH＜2.7，有效氯含量40～50mg/L，于使用前制备。
